I was recently reminded by my friend Nuno that you can actually set the name of the machine used in a Windows Azure Cloud Service (Web or Worker Role).  Normally I really don’t care about the name of the machine.  I’m fine with RD-whatever.

not_set_role_vm_name

If I did care, there is a way to set that machine name.  There is a “vmName” attribute in the Role element of the role’s .cscfg file.

<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="CloudServiceName" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="3" osVersion="*" schemaVersion="2013-10.2.2">
  <Role name="WebRole1" vmName="CollierWeb">
    <Instances count="1" />
    <ConfigurationSettings/>
  </Role>
</ServiceConfiguration>

Doing so will result in the machine name being set to whatever is in the “vmName” attribute, appended with the instance number (0, 1, 2, etc.)

set_role_vm_name
Keep in mind that the “vmName” attribute value must be less than 10 characters.

Note that the role name will still be whatever is set in the .cscfg, appended with the instance number.

role_name

For more on the schema of the .cscfg file, please see MSDN.
